The spatial and temporal evolution of contributing areas: Nippgen et'al, 2015

I am always interested on the representation of topography and their conditioning into the hydrological modelling. I have seen this accepted paper of Brian McGlynn and his co-workers entitled "The spatial and temporal evolution of contributing area". At the moment, I didn't go through it  but the topic is very  interesting, so I am saving to my list to read papers. The introduction section (objective of the paper ) reads as follows:

"Here we present a parsimonious but fully distributed modeling framework that incorporates topographically driven lateral water redistribution and eddy covariance derived spatially disaggregated evapotranspiration measurements to simulate streamflow and the spatial distribution of water stored in the watershed through time. The goal of the model development and this particular application was to inform our understanding of the spatial and temporal dynamics of runoff source areas. Utilizing and testing this diagnostic modeling framework in conjunction with empirical measurements of hillslope connectivity through an extensive network of shallow groundwater wells [Jencso et al., 2009; 2010; Jencso and McGlynn, 2011] we approximated watershed connectivity to investigate how runoff source areas change in space and time over the course of two water years in a snowmelt dominated system."
